We obtain high-resolution echelle spectra of evolved Hipparcos stars within 100 parsec for detailed abundance analysis. We are particularly interested in subgiants because their ages can be derived accurately. Here, we present preliminary results for 10 subgiants and discuss the future work for this project. Our main scientific interest is to incorporate our results to constrain the star formation history in the solar neighborhood.
